DEFINITION MODULE ASCII;
(*====================================================================
    Version : 1.0  Sat, Mar 4, 1989  C. Lins
    Compiler: JPI TopSpeed Modula-2

    INTRODUCTION
    This module provides standard mnemonics for the ISO/ASCII control
    characters and non-alphanumeric characters common to most keyboards.

    REVISION HISTORY
    v1.0  Sat, Mar 4, 1989  C. Lins
      Initial JPI implementation.

    INTERFACE DESIGN ISSUES
    * The mnemonic names are given in all lowercase letters for
      compatibility with other Modula-2 systems.

    * Should the names for non-alphanumeric characters be capitalized?
      The decision was to not capitalize, and use all lowercase letters.
	+ Easier to key without using Shift-Key.
	+ Consistant with mnemonics for control characters.
